RADIATOR-CORE PLATE.

Application filed September 28, 1918.

To all whom it may concern:

Be it known that T, CHAnLns F. SrnnY, a citizen of the United States, residing in the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiator-Core Plates, of which the following is a specification.

Hy invention relates to the plates which serve as connections between the core or radiating element and the water wells of radiators such as are used on automobiles and the like for cooling water circulating through the engine walls.

Prior to my invention the only kind of such plates employed, so far as I am aware, have consisted of a stripdike piece of fiat metal having bolt holes around the margins and a central longitudinal opening which serves, when the plate is in operative position. as a passageway between the water well and the core. Various disadvantages and difiiculties have been experienced in the old construction, such as the prime ones of making a firm, tight and lasting joint between the plate and the core and the necessity for using relatively heavy material for the plate in order to proviee the desired strength.

The principal objects of the present inipro ."ements are to provide a strong and durable core plate of light weight, and one so shaped that a firm and lasting watertight joint may be easily and rapidly made between it and the core. Other objects and advantages will appear hereinafter.

In the accompanying drawings which form a part of this specification, Figure 1 is a fragmentary top view of my improved core plate; Fig. 2 is a side view of one end of the same showing a fragment of a core secured thereon; Fig. 3 is a cross sectional view of the plate showing also a fragment of a core thereon; and Fig. 4 is a cross sectional view of the old form of plate with a fragment of core thereon.

The present improvements in the core plate depart from what is old and well known in the provisions of an offset portion, rib, flange or extension and substantially a channel around the central opening or pas sageway, and in a considerable reduction in the thickness of the material of the plate. As to the latter, I find that one-sixteenth inch rolled plate stock, preferably sheet Specification of Letters Patent.

steel, is entirely satisfactory in sizes where one-eighth inch stock has been commonly used heretofore. This saving in material and, importantly, in the weight to be carried by the automobile or the like, results from the unitary rib, flange or extension which is, preferably, stamped up from the body of the plate and thus forms an integral part of it.

The plate 6 is of the usual contour and will be made to conform to the particular water well with which it is to be used. .lt is also provided with the bolt holes 7 and the central longitudinal passageway 8 as usuj -l. In the device illustrated in Figs. 1, 2 an( 3 the offset portion, rib, flange or extension mentioned surrounds the opening 8 and is next adjacent thereto. It comprises, first, an upstanding part 9 preferably slanting slightly inward (meaning toward the opening 8) on each side of the opening 8 (see Fig. 3) and a similar part 10 at each end (Fig. 2).

In my practice these parts 9 and 10 ordinarily extend upward about three-sixteenths of an inch, but there is no limitation as to degree in this respect. The side parts 9 are continued inwardly to form the part 11 which extends parallel to the body 6 and provides a fiat face or seat, in my practice about a quarter of an inch wide and constituting a strip of considerable area along the sides of the opening 8 adapted to contact end portions of the core, as 13. 1

It is well understood that one core plate is secured to the bottom of the core and another to the top thereof, and that the plates are then secured as by bolts in the holes 7 to the bottom and top wells respectively of the radiator. The plate is preferably treated to an acid bath and tinned.

The only practicable means known for securing the core and core plates together are the ordinary soldering iron and soft solder.

By reference to Fig. 4 it will be noted that in the old practice the solder must be applied to a right-angular space at 16 defined by extensive walls, and to a small corner at 17 defined on one side by the thickness of the metal of the plate 18. At both of these corners 16 and 17, and especially at 16, one difficulty is in heating by means of the soldering iron the plate 18 sufliciently to cause the solder to flow, the plate being usually at least an eighth of an inch thick.

At 16 the application of the solder must be principally with the nose or point of the iron, which has only a limited heated capacity and soon cools. The result is that it is only by slow and repeated effort that the corner at 16 is filled with solder, and this application is substantially only in the corner itself, there being but a limited floiv between the core and the plate where they face each other. At the corner 17, while the iron may be placed flat against the plate so as better to heat it to cause a fiow on the other side it is difficult to heat the mass sufliciently for the desired purpose. Furthermore, the amount of solder at the corner 17 is almost necessarily quite limited as any attempt to build up a mass of solder there is defeated by its spreading over the surface of the plate under the hot iron. It is understood, of course, that the parts are suitably positioned so that the iron is operatively above the work.

Considering now Figs. 1 to 3 inclusive it will be observed that at the joints 19 and 20 the broad face of the iron may be applied directly over the joint, the work being turned, of course, at right angles to the positions shown in Figs. 2 and 3, the rib or offset portion 9 and 10 providing a working space for the iron, and, since the material of the plate 6 may be relatively thin, it be comes sufficiently heated in a short space of time and the flow of the solder penetrates deeply at these joints 19 and 20. Importantly, too, it is feasible to fill in a materially large mass of solder exteriorly at these places since the base 6 there forms a retaining wall which holds the solder until cooled. V

Vhen the work is turned about so that the plate 6 is horizontal and the projections 9 and 10 extend downward, 01' with the position of Figs. 3 and 4 reversed, it will be noted that there is a channel-like formation adjacent to the joint. This channel holds the solder and prevents its spreading while the part 11 is being heated by the iron,

and it is feasible to provide a considerable mass of solder around the end of the extension 11 while inducing its flow between the flange and the core.

The soldering operation at all joints is thus rendered simple, easy and rapid, and the desired strong, tight and lasting construction is effected. The exterior solder is indicated by dotted or stippled areas. No attempt is made to show that which flows between the core and the extension parts.

I have shown the core 13 according to a well known construction. Other types may be similarly applied to the core plate.

I claim:

1. A radiator core plate comprising a substantially fiat plate body adapted to be secured to the radiator water well and hav ing a water passageway therethrough substantially coextensive with the core in the longitudinal direction, and an offset portion on said plate surrounding said passageway, said offset portion having a rest surface thereon for the radiator core.

2. A radiator core plate of the character described comprising a substantially flat plate body having a water passageway therethrough and having a unitary offset portion on one side of said plate and ex tending around said passageway and next adjacent thereto, said offset portion having an inwardly extending part on opposite sides of said opening forming a seat for the core.

3. A radiator core plate of the character described comprising a substantially flat plate body with a water passageway therethrough, and around said passageway a continuous offset portion on one side of said body and unitary therewith, said offset portion having an inwardly extending striplike part adjacent to opposite sides of said passageway and forming substantially the base of a channel on one side of said strip and a seat for the core on the other side thereof.
